Arista DCS-7050TX-64-F - eBay US

[gb00s]

Not exactly sure if this is a super super super cheap deal, but it's still 48x 10G RJ45 ports with 4x QSFP ports. I know they are not super quiet, but turning down the fans to 40% keeps them cool and just slightly audible .... and it's ARISTA All the other ARISTA switches I bought from them were all in super condition.

I was able to catch an offer for US$ 200.00. They, specially Tom, were very helpful with the process while eBay confused everyone again ;(

You should mark this as EU

 

[gb00s]

I don't think so as the seller is from US and just my link is from eBay - Germany.

Upvote for the seller. I buy a lot from them (Dedicated Networks Inc) and never had issues.

Really tempting considering the cost of SFP+ 10GBaseT transceivers...

Any idea how much power these draw at (or near) idle? And how loud are they?

 

[ano]

110-130w estimate at idle
not loud at all, you can force the fans down

Ive also done business with them

what is the difference between tx and just t ?

what is the difference between tx and just t ?

T seems to have Broadcom Trident+, whereas TX has Broadcom Trident II.

Trident II has 33% bigger Buffer (9MB vs 12MB), Trident II supports VXLAN and NVGRE. Trident II has the smart table feature, which allows you to trade e.g. number of routes against MAC address table size etc..

Thanks, nothing major for homelab or small business networks

 

[Layla]

Seller accepted $175 for one

TBH, this seems like a great deal to me - I've been looking for one for a year, and they were selling for $450 not so long ago.

Are these as loud as an ICX6610 or 7250-48P?

Note that listed units have fans that blow front to rear. I like rear to front so I can put cables in back of rack.

Datasheet says 315W Typical / 387W Max. But i guess that is with all ports connected?

and with quite a load.

 

[ano]

I can pull load numbers of similar model, marginally newer from a prod env, they are patching it up next week so I can pull numbers with all ports populated

with 6 ports I read 112w

 

[gb00s]

I've seen these pulling 208-215W with 36x 10G and all 4x QSFP ports connected, Fans down 40% and still cool enough at 52C.

2 to 5 watts for copper (distance) vs under 1w for SFP. There is a reason I use SFP everywhere except for OOB's.

How much did 2x Arista 10G SFP+ transceivers and fiber optic cable cost at the time and how much was electricity in 2014/15?
